My 2007 Land Rover Freelander makes a whistling sound when vehicle is idling. Sound goes away when accelerating or applying petrol?


it may be a turbocharger if so equipted, lots of turbocharged cars whistle as the unit gets older..only other thing I can think of is something with the exhaust system.. get it looked at by putting the car up on a lift and inspecting it..now some cars also whistle thru the radio ..this is called alternator whine and is usually correected by a filter in the power line of the radio...good luck

2001 Jeep Wrangler makes whistling sound except when you accelerate. Everytime you put your foot on the gas, it stops....take your foot off the gas and it whistles


if you have an aftermarket intake on the jeep the throttle body is making the whistle... there are many aftermarket throttle body spacers out there that can eliminate this...
if you dont than I think that we have the same problem... might be a vacuum leak if the jeep idles funny or it could be an exhaust manifold leak... I'll let you know if I figure out mine. :)

Whistling noise when accelerating


you most likely have an aftermarket radio installed
the noise you hear is engine noise, if yo turn your radio off it will go away
this can be fixed by either getting better wiring for your aftermarket radio or by installing a noise filter, you can purchase that at most big electronic stores
